Sorry for the newby questions. Been shooting film and digital for 40+ years and decided to take dive lessons this summer. I plan to get an Olympus TG3 for shallow water diving and snorkeling and will probably get a housing for my old Canon G11. I was wondering if I should get some filters for the tg3 and what filters were commonly used to what depths and water conditions. I will be doing a day dive in Cancun over July 4th weekend and don't want to miss the opportunity for taking the best photos even though I'm just starting out. Thanks for your advice.... H2

I would strongly recommend the cool ring flash accessory that fits the TG-3: website It should be great for macro. You can also get a red filter but it's not that much recommended for shallow / snorkeling. Only 5-15 meters. Shallower than that, your photos and videos would turn out red. Getting is strobe is also recommended, as it is the only way to get the true colors underwater. Get a YS-01 for you G11 and sync it with fiber optic. You can get great photos with a system like that. Last thing - remember underwater photography takes time to master and you have to improve your diving skills first, so don't get discouraged if the images aren't that good at first. It gets better
